I use an MFA Magus B, and also own an Audible Illusions L1. I bought the MFA for the well-regarded phono section, the AI for the headphone amp-but it lacks phono. I recently purchased a relatively high-end phono set up with a low output MC, and also bought an SUT. Obviously, I’m using the MFA now, but I have high regard for both preamps. Since you didn’t give a hint of what you are planning to listen to with the units I’ll just say that, if using analog, I believe that both are good choices.
